43! Description:
44! ------------
45!> Standard kind definitions
46!> wp (working precision) and iwp (integer working precision) are the kinds
47!> used by default in all variable declarations.
48!> By default, PALM is using wp = dp (64bit), and iwp = isp (32bit).
49!> If you like to switch to other precision, then please set wp/iwp
50!> appropriately by assigning other kinds below.
